SF-902S ENGINE DYNAMOMETER The SF-902S engine dynamometer is rated for 15,000 RPM, 1,500 HP and 1,200

lb.-ft capacity. The low inertia design and unique capacity valve make it well

suited for small single cylinder engines all the way up to powerful V8s.

Overview The SF-902S engine dyno houses a new absorber designed for high RPM and maximum

durability. It’s rated for 15,000 RPM, 1,500 HP and 1,200 lb.-ft of torque. PTFE teflon water

seals and high speed ABEC 7 bearings allow the new absorber to run at high RPM for extended

testing periods without issue. The new stainless steel trunnion and backing plate provide a 75%

increase in resistance to cavitations compared to previous aluminum bronze components. In

addition to the new water seals, high speed bearings and stainless steel components the new

absorber in the SF-902S dynamometer includes a hall effect speed sensor for greatly improved

low speed RPM measurement.

The included roll-around engine docking cart offers great versatility to adapt to various types

of engines and its stainless steel runners mean easy adjustment of the engine supports without

any rust. It’s also compatible with the SF-Powermark to allow maximum versatility. The space

saving dynamometer frame provides a convenient tool tray and two bump starters to make

lashing valves easy. Adaptation to the engine is simple with the optional multi-fit bell housing

or the adapter of your choice. To keep the test cell neat, the integrated boom assembly houses

both the sensor box and cooling tower, plus it has cable stays to route transducer wires cleanly

between the sensor box and the engine. The included non-pressurized cooling tower mounts

to the boom assembly behind the dyno, out of the way. The new sensor box also mounts to

the boom where it is kept safely away from engine vibrations and heat. WinDyn’s® pre-defined

test sequences allow for standard tests at the push of a button so you’re up and running

immediately and the live trace feature lets you see live data as a trace over a saved reference

plot.

Data Acquisition

WinDyn Control and Data Acquisition System

SuperFlow’s WinDyn® Software is the

most feature rich system available for

dynamometers today. We’ve

included all the tools you need to

make a SuperFlow® dynamometer a

successful piece of your business.

WinDyn® is preconfigured with

industry standard tests to get you up

and running quickly. But, we didn’t

stop there. We’ve also developed

powerful configuration and test

editors that offer you complete, customized control of the dynamometer, the test cell and the

tests you’re running.

WinDyn’s® available 76 measured channels and 35 calculated channels let you measure and

analyze data to make your products better. Our advanced electronics sample data at rates

between 1,000 and 2,500 Hz depending on the channel and display it at 100 lines per second

so you’re sure to see the entire picture. The built in data analysis tools let you see data in a

way that makes sense, and like the rest of WinDyn®, data analysis is completely user-

configurable should you choose. Start Testing Quickly WinDyn® comes preconfigured with

standard tests to get you testing quickly. Pre-defined test groups automatically configure the

dynamometer for standard testing. Simply select the one that matches your current needs and

you’re ready to run.

Test Groups

A test group is a WinDyn® file that completely configures the dynamometer for testing. By

using test groups you ensure that all tests are run in the same way, regardless of the operator.

Test groups configure the following:

- All channels being monitored (measured, calculations, constants and interpolations)

- Screen group of up to ten real-time data monitoring screens

- Safety limits (if desired) to protect your engine

- Test profiles (acceleration, step, steady state, break-in, life cycle, track simulation,

custom, etc.)

- Sensor calibrations

- Relay controls for test cell functions (lights, pumps, fans, ignition, etc.)

- PID control parameters

- Test specifications (starting and ending speeds, engine specs, test notes, etc.)

Completely Customizable

In addition to the standard ready to run configuration supplied from the factory, you can

customize WinDyn® in any manner you’d like. Write custom test profiles, design custom screen

groups, add a company logo to data plots, setup print preferences for graphs and tabular data,

add additional sensors or integrate emissions equipment quickly and easily. The best part

about WinDyn® is its versatility: it comes fully loaded and ready to run all the standard tests

you need, plus gives you the power to configure tests any way you prefer. Learn more about

our advanced editors.

Test Profiles

Test profiles are a series of commands that automatically perform a test. WinDyn comes

loaded with standard test profiles including acceleration, step, steady state and break-in, but

the Test Profile Editor gives you the ability to write any custom test you can imagine.

Here are some examples of what WinDyn users are already doing-

o Automated one-touch tests that control every detail like-

- powering on pumps and fans

- powering ignition

- turning on fuel

- checking critical parameters like oil pressure and water temperature before

- beginning a test sequence

- ending the test

- stopping the engine

o Cyclic durability tests to check engine belt life

o Reverse acceleration to simulate tractor pulling

o Transmission durability tests on chassis dynamometers

o Slope simulation

o Track lap simulation for the Pikes Peak Hill Climb, Charlotte Motor Speedway and

others

o Pass/Fail tests for air filters and catalytic converters on the SF-1020SB

o Automated chassis dynamometer tests with throttle actuators

o 300 hour diesel engine durability tests

o Urban drive cycle tests

o Emissions tests

Configuration Editor

The configuration editor gives you the power to create the custom test environment you

desire.

This powerful Windows® based editor allows you to define-

o Channel Definition (name, units, format, filtering, formulas, etc.)

o Control Channels (close-loop controllers for load, throttle, flow, etc.)

o Display Channels (in any language)

Once you’re happy with your custom configuration, it’s saved so the dynamometer can quickly

be configured to your specifications before every test.

Safety Limits Editor

Safety limits prevent problematic situations like low oil pressure or overheating from damaging

your engine or vehicle. They are completely user-configurable by channel (exhaust temp, oil

pressure, water temp, etc.), by critical value and by resulting action. You can even setup a multi

stage rev limiter. Limits are constantly monitored and if triggered the post mortem feature

kicks in to provide a snap shot of data before and after the limit was triggered to assist you in

deter-mining what happened to the engine.

Test Data Perfected

WinDyn® is packed with data analysis tools that make analyzing your engine or vehicles

performance easy. For each test you can view up to 10 user-defined pages in tabular format,

graphical format or side-by-side. Additionally, up to 10 saved tests can be overlaid on a graph

enabling you to make informed decisions quickly. Like all other WinDyn® features, all the data

viewing capabilities are customizable. The test group defines which data is on each of the ten



of 13

pages and on each page’s graphs. You can change this at any time, even after the test is

completed.

Want to see an area of a graph in more detail? Drag a box around the area you want to see

and WinDyn® immediately zooms and re-scales that portion of the graph for easy comparison.

Plots are easily enhanced with your company logo before printing. They can also be exported

as a bitmap or JPG for emailing to customers or posting to your website. If WinDyn’s® data

analysis tools aren’t enough for you, export your test data to Microsoft Excel® for custom post-

test analysis.

Customer Data Packs

Your customers are why you’re in business. With WinDyn’s® Customer Data Pack feature you

can instantly create a file with their test data and the WinDyn® data viewer so they can take

their results home. This data viewer includes all the same analysis tools as WinDyn® so your

customers will be assured of their results.

SuperFlow Explorer

Managing data files is crucial to finding your data efficiently. The SuperFlow® Explorer, located

under the tools menu, allows you to quickly navigate to the correct data, view it, plot it or print

it with the click of the mouse. It can browse all folders, networks and the desktop and also

create, rename, copy, move delete and manage all system folders.

Test Playback

WinDyn® allows you to replay stored tests with all meters and screens active just as they were

during the original test. You can print any or all WinDyn® screens and data to most Windows®

supported printers.

Sensor Box

The SuperFlow sensor box is the brain of the 139 channel WinDyn data acquisition system. Its

advanced electronics measures high-resolution data at up to 2,500 Hz depending on the

channel and sends the data to the operator station via a simple Ethernet connection for live

monitoring.

The SuperFlow sensor box houses the data

acquisition and control boards that makeup the 139

channel WinDyn data acquisition system. Its

advanced electronics measures high-resolution data

at up to 2,500 Hz depending on the channel and

sends the data to the operator station via a simple

Ethernet connection for live monitoring. The only

connections between the test cell and operator

control room are three Ethernet cables making

installation simple. The sensor box is modular and is

expandable at any time. Eight expansion bays are

ready to accept expansion panels for additional

temperature, pressure, analog voltage or frequency

inputs. Most SuperFlow engine dyno packages includes a ten-channel pressure panel and a

sixteen channel temperature panel and sensors as a starting point.

The included weather station uses a barometric pressure transducer, air temperature sensor

and humidity sensor to measure atmospheric conditions continuously throughout the test and

calculate the proper weather correction factor. Standards like STP, SAE, ECE and DIN are built

in and user selectable, the configuration editor can also be used to write custom correction

factors.

The sensor box also house the controllers that provide SuperFlow’s legendary closed loop PID

control. Its flexible dual-mode control scheme allows either the dyno or the throttle to control

to speed, torque, power, manifold pressure or any other channel of your choosing.

Sophisticated logic lets each controller use up to four different control modes and parameter

settings.

The sensor box can either be mounted to our test cell boom system or to the wall using the

wall mount bracket.

Control Console

The control console is the

main interface between the

operator and the entire

engine test cell

environment. Front and

center on the console

is a touch screen

where operators select

the type of test and enter

parameters like starting and

ending speeds. When the test

is active on screen prompts

guide the operator through the

test.

Three manual control modes are available using the control know mounted in the console. This

controller allows manual control to torque, RPM or percentage of load which keep operators

in control during break in and warm up routines and when an automated test profile is not

activated.

The engine control panel in the center of the console provides the operator with four relays to

control ignition, fuel pump, starter and one auxiliary button commonly used for electric water

pumps. Four more relays could be added to the console for additional control functionality.

Six rocker switches in both upper corners of the console are used to wire in test cell equipment

like lights, pumps, fans and heaters so you never have to leave the console to start up or shut

down the test cell. A 30ft. wiring harness with mating connector to the console and schematic

is included to wire in your test cell equipment.

Lower right on the console is a keyed power switch to power off and lock-out the dynamometer

at the end of a shift and the large E-stop button will shut down the entire operation in case of

emergency.
